Operation CHARM: Car repair manuals for everyone.

General Information

A permanent magnet motor operates each of the power side windows. Each motor raises or lowers the glass when the motor receives voltage. The direction the motor turns depends on the polarity of the supply voltage. The side window switches control the polarity of the supply voltage.

The left front door lock and side window switch controls all of the motors. The other window switches control only the window regulator motor in that door.

A built-in circuit breaker protects each motor. The circuit breaker opens the circuit when the switch is open for too long of a period of time under the following conditions:
^ The window has an obstruction.
^ The window is fully open or fully closed. The circuit breaker resets automatically as the circuit breaker cools.
